Embodiment

[0012] Embodiment: as shown in the accompanying drawing. The device for preventing intermittent backflow of backwash filter water supply includes a body (1), on which a water supply module (2), a flow limit module (3), a temperature sensing module (4), and a management module (5) are arranged. ), when running, the water flows out from the water supply module (2), and the water flow limit module (3) is set at the water flow turning point or the place where it is easy to return, and the temperature sensing module (4) senses the temperature of the water flow, and the sensed information is provided by the management module ( 5) Processing.

[0013] The backwash filter water supply intermittent backflow preventing device is provided with a pressure sensing module (6) on the water supply port module (2) to sense the pressure value when the water flows out.

[0014] The backwash filter water supply intermittent backflow prevention device is provided with a flow sensing module (7) on...

Abstract

A water supply interruption and backflow prevention device for a reverse-washing filter comprises a machine body (1).A feed water inlet module (2), flowing water limiting modules (3), a temperature sensing module (4) and a management module (5) are arranged on the machine body (1).In the operation process, a water flow flows out of the feed water inlet module (2), the flowing water limiting modules (3) are arranged on the positions where the water flow turns or backflow is prone to occur, the temperature sensing module (4) senses the water flow temperature condition, and sensed information is treated with the management module (5); a pressure sensing module (6) is arranged on the feed water inlet module (2) to sense the pressure value condition when the water flow flows out; a flow rate sensing module (7) is arranged on each flowing water limiting module (3), and the flow rate sensing modules (7) sense water flow rate conditions of all points where the flow rate sensing modules (7) are arranged; a prompt module (8) is arranged on the management module (5).The running effect is prevented from being affected by controlling backflow of the water flow in a pipeline and maintaining a certain water flow rate in real time.

Description

technical field [0001] The invention relates to a water quality purification device. Background technique [0002] The backwash filter is a device that uses a filter to intercept impurities in water. It has the advantages of purifying water quality and reducing dirt. There are still some defects in the water supply during the operation of the backwash filter. Intermittent water supply or backflow of water will have adverse effects on the operation. positive effect. Contents of the invention [0003] The object of the present invention is to provide an effective device for preventing intermittent backflow of backwash filter water supply. [0004] The present invention is achieved like this. The backwash filter water supply intermittent backflow prevention device includes a body, on which a water supply module, a water flow limit module, a temperature sensing module, and a management module are set. A water flow limit module is set at the place, and the temperature sensin...
